What are the system requirements for running Pholcus?

Pholcus is a distributed, high-concurrency, and powerful web crawler software written in the Go programming language. It provides a web UI to manage crawls and can be used as a library as well.

System requirements for running Pholcus are generally modest, but they can vary depending on the scale at which you intend to use the crawler. If you are running small to medium-sized crawls, a standard modern computer should be sufficient. However, for large-scale distributed crawls, you would need a more powerful setup or multiple machines.

Here are the general system requirements for running Pholcus:

Operating System: Pholcus can run on various operating systems since Go is a cross-platform language. It supports:

• Windows
• Linux
• macOS

Hardware: The hardware requirements depend on the scope of your crawling tasks. At a minimum, you would need:

• CPU: A modern processor capable of running Go applications. The more powerful the CPU (with more cores), the better the performance for concurrent tasks.
• RAM: At least 2GB of RAM is recommended. For larger crawls or higher concurrency levels, more RAM may be required to hold the crawled data and to manage multiple simultaneous threads.
• Storage: Sufficient disk space for your crawled data. The space needed will depend on the volume of data you plan to scrape.

Software: - Go: Since Pholcus is written in Go, you need to have the Go programming language installed. Make sure it's a version compatible with the version of Pholcus you are using (usually the latest stable version of Go is a safe bet). - Web Browser (optional): If you want to use the Pholcus web UI, you'll need a modern web browser.

Installation:

1. Install Go: Make sure you have Go installed on your system. You can download it from the official Go website (https://golang.org/dl/) and follow the installation instructions for your operating system.

2. Get Pholcus: You can get Pholcus by running the following command, which uses the go get command to download and install the Pholcus package and its dependencies:

   go get -u github.com/henrylee2cn/pholcus

1. Run Pholcus: Once you have Pholcus installed, you can navigate to its directory and run it:

   cd $GOPATH/src/github.com/henrylee2cn/pholcus
   go run pholcus.go

Alternatively, you can build it into an executable:

   go build

And then run the built executable:

   ./pholcus

Please note that if you are using Pholcus as a library within your own Go applications, you need to import it and use it according to its API.

Remember that when you are web scraping, you should always follow the target website's terms of service, respect robots.txt files, and avoid putting too much load on the website's servers.
